cat motors

Not to stick my nose into the pissing match, but I think we are getting into talking Apples and Oranges. Need to compare in either stock form, or with Similar mods. I am personally impressed with the 500/1040 in stock form. Heck, I am impressed with the 325/600 the my truck came with from the factory.
 
The reason the aftermarket exists now for the ISB is because of how many are on the road in pickups right now.

The cat has plenty of potential you just have to think outside the box. Simply plugging something in isn't going to work.

First of all, define "bomb" for me. The following modifications would be "bombed" enough for me, maybe not up to your standards. 3116 would need a custom ground cam, marine injectors that might need a little work to open up the orifices on the tip, some sort of twin turbo setup (not sure what turbos to use), marine pistons for the low compression, and some governor work to make it turn 3500+ rpm. The HEUI engines could probably get by with stock marine injectors, marine pistons, cam would probably be fine since it only actuates the valves on this engine. Again, some sort of twin turbo setup, and of course custom software. I am not familiar with the Edge boxes for Cat engines, so that may be sufficient, maybe not.

By "bombed" I meant an engine designed for hi performance pulling and drags. Not a tow rig or daily driver, what we had a conversation about in this forum not to long ago...about the electronic vs. mech ISB's. Building a Cat that could compete with the 700/1600 numbers people seem to be making with the 12v ISB's. /forums/images/graemlins/thumb.gif

[/ QUOTE ] That is the headache that I see is associated with building a seriously "bombed" cat. I wouldn't know who to go to to get custom software programmed and Edge does not make anything for a Cat from what I have seen probably because there is no demand for it.

Isnt this the Tow Rig forum? /forums/images/graemlins/confused.gif
 
Once again RJ, you need to do your homework. Edge does make a box for the 3126B. It is not for high performance, it is for people who work their diesels and RV'ers. Adds up to a claimed 40hp and 140ft/lbs of torque. Im amazed you didnt realize that, especially with how much you seem to love your electronic diesels.

Yeah, thats what i thought too.

[/ QUOTE ]THank you for bringing that to my attention, I was not aware that Edge made a box for them and never noticed on their website.

[/ QUOTE ]If you would like to get techinical this whole thread doesn't really belong in this forum, it's better suited for the "diesel" forum IMHO.
 
Well, IF we really want to get technical, this should probably be in the Garage or the Lounge, considering the diesel forum here is for GM stuff. But Im not here to give anyone a hard time.
 
Youre both right, because the original poster was asking about swapping for what sounded like a towing application, and, the 3208, 3116, and 3126/C7 are just as much a GM diesel as the 6.2.
 
Another thing I forgot to mention that I thought might be obvious, but apparently isnt, is making a truck engine with marine parts is just part of it. Just because the marine engine only makes 450 hp and 1040 ft lbs, doesnt mean you cant turn it up past there. On the 3116, you just need to do a little governor work, and on an electronic Cat, you would have to get the software we have at work and change what we call the torque map which sets max fuel for each speed in the engines rpm range. This is probably all the Edge Box does anyway.

[/ QUOTE ]This is what I was pestering you about and wanting to know. /forums/images/graemlins/grin.gif What could you do with the ECM? How far do you think you could take it up?
 
I could do anything I want with the ECM, but not without getting fired /forums/images/graemlins/thumb.gif Oh, I dont know how much they could take, lets just say a lot.

You'd really get fired for messing with an ECM at work?
 
Well, considering what I do now has nothing to do with the C7 program, it would involve me wasting a couple hours of my day tracking down an ECM then flashing software onto it, which if they found out I was doing that they would have grounds for firing me. I like my job, so I am not gonna risk it just for this.
 
I would say that using company resources for personal benefit would definitely be ground for firing.....I thought this would kind of be common sense.... /forums/images/graemlins/dunno.gif
 
I just figured he could hand it off to a buddy at work and ask him to mess with it and give it back to him later. I had no idea that it'd take that much time and be such a big deal.

When I was at work I looked up plenty of parts for myself on company time. I didn't waste a lot of time doing it but in my experience most employers don't mind bending the rules a little bit.

I guess I didn't realize it'd be such a big deal.
 
I think the issue Cat may have is that an employee would be screwing around with proprietary engine management software on company time, when that's not his job. BIG difference when compared to parts lookups.

I'm sure the engine mfgr's just love the fact that a lot of these mod boxes for electronic diesels can simply be unplugged and "disappeared" if a motor breaks during the warranty period, too.
I have heard a rumor that both D/C and GM have modified the engine controllers for the CTD and the DMax this year, to be able to tell if a box has been installed. Whether this is true or not... I don't know.
